I might be in the minority here...but "Kind of Blue" in regards to recording quality is not that great and vastly overated IMHO...I have the 20 bit remaster and the SACD...the horns are recorded a bit "hot" and distort from time to time...it is an incredible performance though...Miles' career is both brilliant and erratic...the 2 disc "essential" Miles Davis would be a good starting point...
